DSB221SDN 38.400MHZ 3.3V 0.5PPM from KDS Daishinku, in a SMD2520-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | On the TCXO DSB221SDN without stand-by this pin is connected to GND; on the VC-TCXO it is Vcont and on the DSB221SDNB it is ENABLE/DISABLE. |
| 2 | GND | power_in | Ground connection of the oscillator. |
| 3 | Output | output | Clipped sine, DC-coupled frequency output of 0.8Vp-p min. (f≦52MHz) into a 10kΩ//10pF load. |
| 4 | Vcc | power_in | Supply voltage pin for a range of +1.68 to +3.5V (3.3V nominal for this MPN), with max. 2.0mA consumption for 26MHz<f≦52MHz. |
